Our Koheras lasers are deployed for interferometric and distributed acoustic sensing systems which use optical fibers as sensors. The fiber acts as a long acoustic sensor and picks up any acoustic disturbance or perturbation along the line. Long range and high sensitivity The intrinsic low phase noise, the narrow linewidth, and the long coherence length of the Koheras lasers make them ideal for interferometric sensing systems with high demands to dynamic range and sensitivity. The lasers make it possible to monitor large areas – tens of kilometers – with a single laser source. The Koheras laser has played an important role in this application area due to its industrial design, inherent low noise properties and stable performance that is unaffected by different environmental conditions and wide temperature ranges in the field. Robust, reliable, and a long lifetime Our fiber laser design is inherently compact and robust. It is developed for a long lifetime in demanding environments where uptime is critical. With documented low failure rates, we proudly deliver the most reliable low noise lasers on the market.

Koheras HARMONIK HP H69 – 689/698 nm high-power fiber laser Are you looking for a high-power 689 nm or 698 nm laser system for narrow transition elements like strontium? The Koheras HARMONIK HP are single-frequency, mode-hop-free, and ultra-stable fiber lasers. Engineered for high-power and narrow-linewidth light at precise atomic transitions, they are ideal for quantum applications. Experience excellence with Koheras HARMONIK HP lasers, ideal for quantum computing, sensing, metrology, and communications. Featuring a robust single-frequency design, low phase and intensity noise, high OSNR, and industrial-grade reliability. Key Features: - 10 W output power - Narrow linewidth - Mode-hop-free operation - Excellent beam quality, M2 < 1.1 - Low RIN - Excellent pointing stability Industrial reliability: We know that uptime is important to you. Our Koheras fiber lasers are inherently stable. They are reliable, alignment-free, and maintenance-free. You can mount them in a rack or place them upside down, they just do their job. Others even trust our Koheras lasers enough to send them into space. And should you need support, we have a team of dedicated engineers ready to help. 15,000 Koheras lasers have been installed in demanding industrial applications for decades. Now, they are ready to assist you in your quantum research. Ultra-low noise: The HARMONIK HP systems offer an ultra-low phase noise as well as low RIN. The RIN is preserved from the pump laser while the linewidth is doubled. Unique fiber delivery system: Do you want to mount the laser system in a rack? No problem. With the unique fiber delivery system, you can get light wherever you want. The fiber delivery solution handles high power, preserves the low-noise laser properties, and delivers single-mode light at all wavelengths. Fast wavelength modulation: The systems are equipped with easy and user-friendly fast wavelength modulation. This feature is typically used to lock the laser to an external stable reference — such as an atomic transition line or interferometer — to obtain even higher wavelength stability than provided by the free-running laser. The HARMONIK systems offer a 15 GHz mode hop-free tunability with a 10% power change. Thermal tuning: All Koheras fiber lasers are equipped with thermoelectric temperature controllers (TECs). The TECs stabilize the operation of the laser and make it insensitive to environmental temperature fluctuations. The TECs also make it possible to tune the center wavelength by changing the operating temperature of the laser. At standard room temperature (around 20-30°C or 68-86°F) the HARMONIK HP H63 can be thermally tuned to an industry-leading 400 pm. Free-space or fiber output: As default, the HARMONIK HP systems come with free-space output. If fiber coupling is needed, we can propose an efficient coupling via our unique polarization-maintaining single-mode photonic crystal fiber that ensures high-power delivery. Our pre-angled fiber couplers are easy and fast to align. They give a very high coupling efficiency, which does not decrease significantly over time, so it is possible to obtain a long-term stable coupling. Looking for a Titanium-Sapphire substitute? You can successfully replace Ti:Sapphire lasers with Koheras HARMONIK HP fiber laser systems to get a stable alternative with high power and a narrow linewidth.
